Post your best budget mods! ($50 or less)

[Longhorn Man]

OK, some threads have been done in the past on the topic, but I want to throw a new twist on it... this is for everyone, but more for the flat broke crowd.

Many of us have a 3 day weekend coming up, and we might even get some quality truck tinkering time. Assuming you aren't doing booring crap like replacing the bolts that fell out of your fan clutch, you probably want to do upgrades, restoration, or simply, modifications.
But what's a broke SOB to do?

I was everyone to list favorite mods for under $50.
I've always said, one man's budget bolt on, is another man's budget. A very common area that this is true is when someone wants a simple 2 inch drop. Guys come out of the woodwork saying how 'affordable' drop spindles are... or drop springs. I haven't priced them for a few years, but I think they are 200-ish and 100-ish for those 'affordable' pieces. Chopping the spring is free, and despite common opinion, perfectly safe.
Now, lets set some ground rules for what is considered a $50 mod.
Obviously, a person with a pole barn packed with a lift, $25,000 worth of tools, a plasma cutter and 220volt miller MIG welder can get anything done. They have the tools to take junk metal and turn it into a one off treasure. Same with the guys who can paint like Chip Foose.
Lets keep this simple.
#1... 50 bucks is 50 bucks. Not 50 bucks plus this $300 piece "I had laying around" Now a $300 piece that you scored for $50 on Craigslist or at a flea market is fair game.
#2... Cheaper is always better.... free is best.
#3... Hand tools only. If you used air tools to make/modify something, then it is out. HOWEVER... if it could have been done with hand tools, then it's cool and it is back in.
#4... Lets keep it simple, something the average moron with little tallent (like me) can do.
#5... a quick overview, or a link to step by step instructions is best, so this thread doesn't become a 30 page thread that you have to sift through to find that trick you need.

With any luck, this will be a cool list of tips and tricks that we can refer to for years to come.
